Handling errors

If an error occurs in a listener, you can handle it directly using a try/except block. Errors associated with your app will be of type BoltError. Errors associated with calling Slack APIs will be of type SlackApiError.

By default, the global error handler will log all non-handled exceptions to the console. To handle global errors yourself, you can attach a global error handler to your app using the app.error(fn) function.

@app.error
def custom_error_handler(error, body, logger):
    logger.exception(f"Error: {error}")
    logger.info(f"Request body: {body}")
